目前我国岩心钻探工程中广泛使用着各种类型的钻机和泥浆泵等钻探设备.这些设备类型的钻机和泥浆泵等钻探设备.这些设备如何合理地应用于钻探生产,就需要通过计算,掌握其工作能力和所需功率,依设计钻孔深浅来选择与配套使用.一钻机升降系统的计算钻进时,提升及下降钻具的载荷靠升降机承担.各种钻机单绳最大提升能力均有一定限度,例如XB—300型钻机为1500公斤,
At present, various types of drilling equipment such as drilling rigs and mud pumps are widely used in core drilling projects in our country, and drilling equipment such as drilling rigs and mud pumps of these equipment types are well used in drilling production and need to be calculated and mastered Work capacity and required power, according to the design of drilling depth to choose and supporting the use of a drilling rig lifting system to calculate the drilling, lifting and lowering the boring load borne by the lift.A variety of rigs to enhance the maximum capacity of a single rope Limits, such as the XB-300 drilling rig is 1500 kg,
